Remarks
A pen flick is a unidirectional pen gesture that requires the user to contact the digitizer in a quick, straight flicking motion. A flick is characterized by high speed and a high degree of straightness. A flick is identified by its direction. Flicks can be made in eight directions corresponding to the cardinal and secondary compass directions.
When a pen flick occurs, Windows first notifies an application by sending a WM_TABLET_FLICK message, which a window receives through its WindowProc function. Return the FLICK_WM_HANDLED_MASK constant, described in Flicks Constants, to indicate that the application responded to the WM_TABLET_FLICK message. If the application does not return FLICK_WM_HANDLED_MASK, Windows performs the default action specified in the flicks control panel by sending a follow-up notification, such as WM_APPCOMMAND, WM_VSCROLL, or WM_KEYDOWN, depending on which action is associated with the pen flick.
Use caution when handling the WM_TABLET_FLICK message. WM_TABLET_FLICK is passed via the SendMessageTimeout function. If you call methods on a COM interface, that object must be within the same process. If not, COM throws an exception.
